Calibration Algorithm for Array Antenna in TD-SCDMA System
摘要
Abstract
Because inconsistent channel amplitude and phase of array antenna of TD-SCDMA affects the antenna system performance, array antenna channel inconsistency calibration algorithms based on the combination of different reference signals and J. C. liberti algorithm were proposed. The parameters uncertainty of array antenna was corrected by computing estimate value of direction- of- arrival estimated- angle of the reference signals, and the sum and difference beam of channel correction was achieved by beamforming algorithm. The simulation results show that the algorithm can greatly improve the DOA estimation accuracy on the one hand, and the sum and difference beam pointing accuracy of single pulse is improved on the other hand.关键词
